Professional FAQs
Why choose the 0.5-meter cable length?
The shorter 0.5m (20″) cable is perfect for compact control panels or when the monitoring module is mounted very close to the sensor. It reduces cable clutter and loop management.
What does “110 mm Overall Case Length” mean for installation?
It is the total physical length of the probe’s metal body. This dimension helps you verify it will fit into the prepared mounting hole or housing without interference.
How are orders processed and shipped?
Orders are processed quickly. We ship internationally using reliable express carriers: FedEx, UPS, and DHL. Tracking information is provided for all shipments.
What is covered under the 12-month warranty?
The warranty covers defects in materials and factory workmanship for one year from the purchase date, providing full peace of mind.
What’s a critical pre-installation check often missed?
Always measure the resistance of the new probe before installing it. A reading of approximately 4.0 ohms between the center pin and outer shell confirms the probe is electrically sound before you put it in a hard-to-reach location.
Can this probe be used for axial thrust measurement?
Yes, but ensure the target area is flat, perpendicular to the probe axis, and large enough (≥13mm diameter). For small shafts, a reduced gap may be necessary for accurate scaling.
How to Select This Model
Choose the 330903-00-11-05-02-05 when you need a standard M8 probe with a short 0.5m cable for local mounting. It is the go-to choice for upgrades, replacements, or new builds in chemical-resistant applications.
